' "The present invention relates to labeling machines andthe' primary object of the invention is to provide a machine for automatically applying'labels to packages or receptacles ina neat, quick and'eflicient manner without requiring manual handling of thefpackation." r v s a ,A further object of the invention is to provide a labeling machine ofjsuch construction that the packages are" fed'thru the machine in such an angular position as to 'fac ilitate proper and effective applying and sealing of the labels to'the packages.

" 'A further object of the invention is to proembodying novelly operating paste applying, label applying, and label aflixing mechanisms which successively ages' or containers during the labeling oper- V and automatically act upon'the receptacles as moved With an intermittent movement thru the machine. i

"-A still further and important object of the invention resides in the novel construction of the label applying gun.

()ther objects and advantages of the inven tion will be apparentduring the course of the folloivlng detailed de'scrlption, taken in connection with the accom an in drawin sforming a I which drawings: 7

Referring to the drawings in detail, and

wherein similar reference characters designate correspondingparts thruout the several views, the letter A des1gnates a conveyor rack along one side of the rack Afor supporting the paste applicator C, label gun D, label sealing means E, said apparatuses C, D and Ebeing related inthe respective order given from the feed to the dischargeend of the designate a feed transfer for transferring the receptacles or packages'frointhe feed conveyor G, and H'the dischargetransferfor removing the labeled packages from the conveyor rack to a position upon the receiving conveyor or rackJr The *conveyor rack A for receiving and supporting the packages in positionsto have labels 'afi'xed to one end thereof, includes a supporting frame embodying a pair of front and rear supporting rails'5 and 6 respectively provided with rollers 7 permitting free and easy movement of the packages along the supporting rails. These supporting rails 5 and 6 as will be observed in Figures 3 and 4 are arranged with the rearsupporting rail 6 at a higher elevati'onth'an the front supporting rail 5 and with the axes of -the rollers of the respective rails axially aligning; The

rails?) and 6 may be mounted upon the upper ends of suitable uprights 8 arranged ably spaced: points along the rails.

at suit- At the forward ends of the rails and 6, the rails ex tend downwardly as shown'in'Figure 2 to a position at one side of the feedconveyor G so that the packages when positioned on the conveyor rack by the feed transfer F may easily rise intoposition. upon the transversely c vconveyor rack, and upon tl18-'1IlCl1H6d portion B! is mountedthelabel gun D andlabel seal a ,ing means E. l

inclined runway formed by the supporting rails 5 and 6. Supported also upon the upper I ends of the uprights or standards '8, are front and rear guide rails 9 and respect vely provided thruout theirlength withanti-friction rollers 11 adapted to engage opposite ends of the package or container and" prevent movement thereof transversely across the supporting; rails 5 and;6. As will be observed in Figures 3 and 4 the package or container 'P moves thru theconveyor rack or inclined runway in an angular position to the horizontal with the package having a nor'mal tendency to move into engagement with the rollers of the front guide rail 9. The guide rails 9 and 10 are of course arranged at angles above the supporting rails 5 and 6 and by observingFigures 3 and 4=-it will be seen that therollers of the rearguide rail engage sub: stantially at the medial height of the package while the rollers of the front guide rail en gage the front end of the package" at a-posi-z 'tionrelatively near the top edge thereof so as to not interferev with and allow for labels of asize substantially equal to the end dimensions of thepackage to be affixed to the end a of the package. That end of the front guide rail 9 at the feed end of the conveyor rack is extended downwardly and across the forward end of the feed conveyor G whereby the packages when moved down theprefere ably inclined feed conveyor Gengage the 'downturned; end ofthe guide rail and are stopped at a position to be elevated upon the conveyor rack by the feed transfer F. At

7 the delivery end of the conveyor rack the rollers '77 are eliminated from the supporting rails'5 and6 and the railsare slightly upwardly v offset to. provide slides 12' having their upper edges extending substantially flush with theupper edges of the rollers-7.

These slides 12 are vintended to receive and support the packages at the delivery end'of the conveyor rack after thelabels have been affix'ed to the packages. Since the slides12 are at unequal elevations it is preferred that the front guide rail 9 be extended as shown in 7 Figures 1 and 2 for preventing the package from sliding transversely off the slides due to the angular position of the package upon the slides The packages after having the labels affixed thereto are moved upon the slides 12 from which they are liftedby the discharge transfer H to a position upon the receiving conveyor or rack J. r

; The nounting table or frame 3 which is arranged along the front sides of the machine for the gearing for driving the feed and dis:

aside from serving as a support for the devvices C, D and E also serves as a mounting charge transfers F and H-respectively. The i intermediate portion of the table B is pro vided with an inclined 'portionB which is inclinedat "an .angle correspondingto the angle at which the packagespass thru the M unted horizontally along the forward 7 suitable'speed reducing gearing drivenby a source of powersuch as an electric motor 16.;

Referring now to revolving feed transfer F for transferringthe.packages to be labeled from the feed conveyor; G to a positionupon edge of the table as in suitable bearings 13 V is a main drive shaft'l l one end of which exs tends into a suitable gear case 15 contain ng 7 the conveyor rack A, the same preferably mounted adj acent oneend' upon a rotating shaft 18 extending transversely'beneath the supporting rails 5 and 6 andpreferably indined at anangle corresponding to the in- I consists of a pair of transfer arms '17 spect to the feed conveyor G that upon rotation of the shaft'in the direction of the ar- 1 row shown in Figure 2, the longer ends of thearms will move upwardly thru the openings'QO provided in the feed conveyorand ice engage beneath the package for elevating the same into position upon the conveyor rack. A As the transfer continues rotation, the arms 17 carry the package past the paste applicator C fora distance as shown by the dotted.- position of the package P in Figure 1. The transfer shaft 18 is preferably rotated continuously inone; direction by means of "a bevel gear 21 meshing withfarbevel gear 22 mounted upon the forward end of the main H driveshaftl4.

Arranged in the path'of movement ofthe packages by the feed. transfer F, is'a pivoted keeper unit 23 embodying a counterbalanced roller 24: which is depressed when the package is moved over the keeper unit, and when the packagelias reached its limit of movement by the transfer, the counter-balanced roller is raised to itslnormal position and bears aga nst the package for preventing return movement thereof along the conveyor rack. Limited rearward swinging of the unit 23 is obtained by means of a suitable cross bar or stop '24 carried by the support 25 for the unit. As will be observed in Figure 1, the transfer arms 17 move one at each side of the keeper unit 23.

The label gun D for applying labels to the paste coated ends of the packages is mounted in an inclined position upon the forward portion of, the inclined table portion B and includes-aholder32 in which is arranged a I stack of'labels33tobe applied to the pack ages; The holder 32 is mounted for sliding and these springs act to 1 normall movement in suitable guide plate 34 provided with upstanding guide bearings 35 and- 35f As willbeobserved in Figure 5the holder 39- is-slida-ble toward and away fromthe paste coated end of the paelrage'Pbeneathithe front'guide rail 9 of the rack A. Fitting Withinthe holder 32 is a follower plate 86- which bearsagainst the stack' of labels, and acting upon the rear sideof-the plate 136 are suitable leafsprings 37 prefer- *l ably secured totherear wa'll of the holder yurge the stack of labels forwardly" in the holder.

While the angular inclined position of the holder will prevent the front label from fall.-

' ,ingfrom the holder it is preferred that a slightly turned' edge as at38 in Figure 11 be'provided for preventing possibility'ofthe labels sliding out of the holder; Slidably mounted in a suitable guide .39 adjacent the lower end ofthe inclined table-portion B" 1 is] a slide-block 40 which is acted upon by a cam 4I mounted onthe main drive shaft 14 r for forcibly moving thebloclrtoward the M label holder 32. Rigidly attached at one end to the rear Wall of the'label holder 32 is a telescoping push rod embodying rod'sections 4:2'Eil1(l43. The outer rod section 42 which is attachedto the holder 32- has a sliding bearing thru the guide 35jWhile the rod section 48'Wli-ich telescopically fits into the rod seca locationwhereby I 7 he packagesf past the applicator asthe adhesive is- ='being applied; tothe package. The paste applicator preferably 1 embodies a" substantially 'frusto conical: paste roll 26 adapted} to be revolved 1 by-"a; shaft 27 s'uitably gear'ed as at 28110 the tion 42' ,ek tends: freely thru*the-==guide 35 and has its end normally bearing against the rear faceo'f the slide block-40. combined. return and'take-up means is provided for: the

push rod for returning the'label holder to 7 coated end of the package: whereby the front or outermost label will adhere to the paste and be Withdrawn from the: stack of labels.

.The springs will allow for complete rotation of the cam Without any Wedging action occurring and as the throw side ofthe cam recedes from the slide block-40 the spring 44 and 45 will act to respectively Withdraw the label holder and alsoreturn the, rod section43 intocngagenientwith the slide block,

Andi cladvancing means is also embodied in the label 'gun for reducing the required throw of thecam4land also maintaining a substantially equal pressure on vthepack of. labels 33 at eachthrow ofthegun as Well as giving. anyeven-rpressure'on the labels. when the holder is retracted, and also regardless of the quantity of labels in the holder. This means comprises a take-up rod embodying a pairof inner and outer telescopicallyrelated rod sections 46 and 47 respectively, arranged in 1 parallel horizontal alignment above the telescopic push rod'sec'tions 42 and 43. The outer take u'p rod section 47 slidably extends thru the rear wall of the labelholder 32 an; guide 35-; and the inner-end of the same is attached as by a spring 48. tothe follower plate 36.; The inner rod section 46 which has a slid 32.movedinto engagement with thepaste ing fit-in the rod section 47 slidably extends slide block 40 is slightly greater than the spacing between'the open end of the label holder-32 and the end of the package to be Y labeled so thatthe label holder is moved into engagement With the end of the package prior to any movement imparted to the. take-up rod.

. Take-up ratchet means 50 is provided in the advancing rod for maintain ng anteven pres sure on the pack of labels as the labels are used up, and this means is shown in detail in Figure 7' wherein it will be seen. that the rod section 46 is provided on its upper side Witha series ofratchet teeth 51 engaged by a se'rie's ofsp'ring'pressed keepersio'r dogs52 slidably therod section-47. ..As will be observed in.

supported-to extend thru the upper side of Figure 7 .the spacing of the spring. pressed. keeper's or dogs 52 is'unequal to the length of the ratchet teeth 51 so that'the keepers will alternately" actto engage inthe ratohetteeth upon very slight advance movement of the. rodsection .47 longitudinally awayfrorn the rod section 46. An'expa'nsion coil spring 53 sets to normally'return the rod section 46 to its normal position in a manner as will be perfectly: obvious from Figure 5. The spring 48 g aside from relieving any undue .shockfor strain upon the keepers 52 also acts by reason of its being connected between thetake-up rod and follower plate 36 asmeansfor ad vancing the rod 'section47 asthe labelsare used upby reason of the springs 37 exerting a forward pullon the rod section '47 .thru their action upon the follower plate 36. As the advanced against-the follower slide block 40 isnloved by the cam 41 the keepers 52 will cause the rod section 47-to' be plate 36 and thus firmly press the pack of labels against the paste coated end of thepackage;

Referring now to the label sealing means.

E for firmly afiiXi-ng the labels to the packages, the same is shown in detail in Figure 6 and'is mounted upon the inclined portion 13.

of the table B to the rear of the label gun D.

The sealing means E includes a case 55 slid ably mounted in a guide plate 56 provided withv an" upstanding guide 57. Slidably mounted in the case 55 is a presser plate 58 provided at its rear-side with a marglnal flange 59 which engagesbehind a sealing rim same forwardly in the case v fixed to the rearv wall'of' the case 55 1s a teleg 60 shown in Figure 9 having a series ofrelatively small teeth 61 provided on its outer edge. "The sealing rim 60 is removably held within the case55 by suitable set screws 62 and as will be observed in Figure) the sealing ,rim permits outward movement of the presser plate 58.1 Secured to the rear wall of the case 55 are suitableleaf springs 68 which act upon the presser plate 58 for normally urging the scopic plunger rod'embodying inner and outer rod sections 64 and 65 respectively, the rod] section 65 having sliding movementthruthe guide 57 and the rod section 64 being normally in contact with the rear side of the slide block 66 having sliding movement in a guide 6'7 mounted on the inclined table portion-B.

The slide block' 66 is engaged-by a cam 68 Y mounted on the main drive shaft 14 whereby upon rotationof the cam the slide block is forcibly movedtoward the guide 57 A combined relief and return means is provided'for the seal operating plunger rod and consists of a pair of expansion coilsprings 70 and 71 the former of which encircles the rod section 65 with one end acting'upon the guide 57 and.
